MEANS FOR SECURING AN ELECTBIp-LAMP REGEPTACLE TO A SUPPORT.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed April 19, 1907. Serial No. 369,058.

To all whom it may concern: I

Be it known that I, ROBERT P. SCHRIVER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Means for Securing Electric-Lamp Receptacles to a Support, of which the following is a specification.

The recepatcles for incandescent electric lamps are usually made of porcelain, or other nonflexible material; and in mounting the receptacles upon a suitable base, screws are employed, which draw the receptacle and base into close engagement with each other. A serious objection to this manner of mounting receptacles, has been the fact that, in tightening the screws, the receptacles were frequently broken, owing to their nonflexibility.

The object of my invention is to overcome this objection by providing a simple and efiicient means for securing a receptacle to a support, which means will adapt itself to any irregularity between the receptacle and support. A further object of the invention is to provide a water-tight joint between the receptacle and its support, all as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is an elevation of a receptacle, a support therefor, and my improved means for securing the receptacle to the support. Fig. 2 is a sectional view, as on the line 2-2, of Fig. 1. Fig. 3 is a sectional view as on the line 3.3, of Fig. 2.

4 designates a well known form of receptacle for incandescent electric lamps, said receptacle comprising the socket body portion, 5, and the exterior flange 6,

' by means of which the receptacle may be secured to a support. 7 designates a flat bar upon which the receptacle 4 is mounted.

A portion of the receptacle 4 extends through an opening in the bar 7, and one face of the flange 6 rests against one face of the bar 7.

My improved means for securing the receptacle 4 to its support, or the bar 7, is of the following construction: i

8 designates a band of sheet metal, extending around the flange 6, a slight distance from the outer surface thereof. This band 8 is provided with a flange 9 extending inwardly from one of its edges, and with a flange 10 extending outwardly from the other of its edges. The-fiange'9 of the band 8 engages the face of the flange 6 of the receptacle, away from the bar 7; and the flange 10 is adapted to engage or lie very close to the bar 7, the flange 10 being secured to the bar 7 by means of solder 11.

In order to provide a water-tight joint between the receptacle 4 and the bar 7, I interpose between the band 8 and said receptacle, a filler of white lead, or other suitable material.

In assembling the parts, the band 8, with its flanges, is applied to the receptacle 4; the white lead or other material is then introduced to the space between the band 8 and the receptacle. The parts are then applied to the bar 7, and the flange 10 soldered to said bar, as shown. The receptacle may be readily removed from the bar by the application of heat to melt the solder 11.

From the foregoing description, it will be seen that a perfectly Water-tight joint is secured between the receptacle and its support, and'that there need be no undue strain upon any part of the receptacle, by reason of the fact that the solder will compensate for any irregularities between the receptacle and'its support. Thus a suitable means is obtained for securing the receptacle to its support without liability of breaking the receptacle.

I claim:

1. The combination, with a flanged receptacle for electric lamps, and a support therefor, of a member engagedwith ,said flange and soldered to said support.

2. The combination, with a flanged receptacle for electric lamps and a support therefor, of a band surrounding said flange and engaged therewith and soldered to said support.

3. The combination, with a flanged receptacle for electric lamps, and a support therefor of a member engaged with said flange and soldered to said support, and a filler interposed between said member and flange.

4. The combination, with a flanged receptacle for electric lamps and a support therefor, of a band surrounding said flange and engaged therewith and soldered to said support, and a filler interposed between said band and flange.

In testimony whereof I afiix my signature in presence of two witnesses.

ROBERT P. SCHRIVER.
